2020年12月1日 · Synthesis of PMN-PT relaxor thick films invites special attention, as the electromechanical response exhibited by the polycrystalline PMN-PT film greatly depends on the thickness of the film. PMN-PT films with a thickness of approximately one micron are required for optical applications as well [6].

2024年10月22日 · Herein, we successfully demonstrated a flexible piezoelectric nanogenerator (PENG) designed by the co-doped rare-earth element ceramics (RE-PMN-PT) embedded in PVDF and PDMS composite film and attained a significant output performance while avoiding electrical poling process.

2022年1月24日 · In this work, we used a combination of diffraction and spectroscopic techniques to elucidate the structural information at different length scales of epitaxial relaxed PMN- x PT thin films with compositions around the bulk MPB, namely, PMN-25PT, PMN-33PT, and PMN-40PT.

2021年10月14日 · The optimal ferroelectric properties of 2% Fe-doped PMN-PT thin film annealed at 650 °C were identified with slim polarization-applied field loops, high saturation polarization (Ps = 78.8 µC/cm2), remanent polarization (Pr = 23.1 µC/cm2) and low coercive voltage (Ec = 100 kV/cm).

In this work, an all-inorganic transparent Sm-doped Pb (Mg (Sm:PMN-PT) film has been successfully grown on Mica substrate via a simple one-step sol-gel process. The flexible film shows an ultrahigh piezoelectric coefficient of 380 pm V −1 owing to the enhanced local structural heterogeneity and the weak substrate clamping effect.
